Climate

Kumagaya has a humid subtropical climate (Köppen climate classification: Cfa) characterized by warm summers and cool winters with light to no snowfall. The average annual temperature in Kumagaya is 14.0 °C. The average annual rainfall is 1532 mm with September as the wettest month. The temperatures are highest on average in August, at around 25.8 °C, and lowest in January, at around 2.4 °C.[2]

Kumagaya is known for being one of the hottest areas in summer in Japan. This is caused by very hot winds from Tokyo and the Chichibu basin in the west of the prefecture. In central Tokyo, the summer monsoon enhanced by sea breeze is heated by the urban heat island. Also, from the Chichibu Mountains, the Föhn blows. The two winds converge above the city at about 2 p.m.

On August 16, 2007, the city recorded air temperature of 40.9 °C (105.6 °F), breaking the 74-year record for the highest temperature recorded in Japan. "Very Hot! Kumagaya" (あついぞ!熊谷) is a catchphrase of the city.[3] On July 23, 2018, the national record was broken again with a temperature of 41.1 °C (106.0 °F),[4] surpassing the previous record of 41.0 °C (105.8 °F) recorded in Kōchi Prefecture in August 2013.[5]

There was a large hailstorm on June 29, 1917 at about 5 p.m. The hailstones had a diameter of 29.5 centimetres and weighed 3.4 kilograms.[6]

The Japan Meteorological Agency maintains a local meteorological observatory in Kumagaya.

History

Kumagaya was part of ancient Musashi Province and was controlled by various samurai clans from the Heian period. One of these clans, the Kumagaya clan, rose to prominence during the Kamakura period. During the Edo Period, the area was divided between the holdings of Oshi Domain and tenryō territory under direct control of the Tokugawa shogunate. Kumagai-shuku developed as a post town on the Nakasendō highway during this period. After the Meiji restoration, the town of Kumagaya was established with the creation of the modern municipalities system on April 1, 1889.
